Automated input and output in FactSage – Part I

Tabular input for automated calculation with FactSage.

A customer has asked me: “Is it possible to export/import data to and from FactSage? For instance, I would like to do a series of calculations for different initial chemical compositions of the system and it would be very useful to import all the compositions automatically from an Excel table into FactSage”. Yes, it is …

From molar Gibbs energy functions to phase diagrams – Part I

Al Cu Phase Diagram

In a series of posts, we will focus on the relation between phase diagrams, Gibbs energy functions and activities. Let us begin with the Al-Cu phase diagram at a temperature of 500 °C. In this blog post we will work exclusively with the FactSage Education Package. Let us suppose we have generated an Al-Cu phase-diagram …

Including extra data points in FactSage figures

Inserting extra points on diagrams - with legends

A customer has asked me: “How can I include an experimental point on a figure generated in FactSage ?”. The procedure is relatively simple. Suppose that you have generated a curve in FactSage like the one below. Representing the Molar Gibbs Energy of the γ phase in the Fe-C system at 1000°C as a function …

A hands-on example for an equilibrium-module calculation

FactSage contains many modules. The major ones for daily work are Equilib and Phase Diagram. In the Equilib module, global Gibbs energy minimization is used to determine the equilibrium state of a complex chemical system defined by its chemical composition, temperature and pressure. Equilib is easy to use: First, the chemical system has to be defined …

Casting Case Study: Refractory-melt interactions

Casting with bottom teeming

In the scope of the collaborative research center SFB 761, von Schweinichen(*) experimentally investigated the chemical interactions between a high manganese steel melt and different refractory materials employed in assembling an adequate casting system. Normally, when casting in an open atmosphere, one expects worse results considering cleanliness for a top pouring process (Figure 1) than …

How do I add “Balance” as amount for Fe?

I have just been asked by an experienced FactSage user how to add “Balance” when specifying an alloy composition in FactSage. This is one of the features that is very useful but unkown to many, so we should explain it better! This is why we started the GTT-blog anyway… So, let’s consider the case when …
